模板（自定义base.html）

1、hello.py

from flask import Flask, render_template
from flask.ext.script import Manager
from flask.ext.bootstrap import Bootstrap

app = Flask(__name__)

manager = Manager(app)
bootstrap = Bootstrap(app)

@app.errorhandler(404)
def page_not_found(e):
return render_template('404.html'), 404

@app.errorhandler(500)
def internal_server_error(e):
return render_template('500.html'), 500

@app.route('/')
def index():
return render_template('index.html')

@app.route('/user/<name>')
def user(name):
return render_template('user.html', name=name)

if __name__ == '__main__':
manager.run()

2、base.html（自定义）



base.html:

{% extends "bootstrap/base.html" %}

{% block title %}Flasky{% endblock %}

{% block navbar %}
<div class="navbar navbar-inverse" role="navigation">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="/">Flasky</a>
</div>
<div class="navbar-collapse collapse">
<ul class="nav navbar-nav">
<li><a href="/">Home</a></li>
</ul>
</div>
</div>
</div>
{% endblock %}

{% block content %}
<div class="container">
{% block page_content %}{% endblock %}
</div>
{% endblock %}
